An airline pilot pulls her 12.0 kg rollaboard suitcase along the ground with a force of 25.0 N for 10.0 meters. The handle she pulls on makes an angle of 44.0 degrees with the horizontal. How much work does she do over the ten-meter distance?

  1. Fh = 25cos44 = 17.98N.

    W = Fh*d = 17.98 * 10 = 179.8J.
